Hyaluronic acid formulation of near infrared fluorophores optimizes surgical imaging in a prostate tumor xenograft

Abstract: We have demonstrated the potential of a panel of near-infrared fluorescent (NIRF) nanoparticles (NPs) for image-guided surgery in a prostate cancer xenograft model. Image-guided surgery and imaging of organs ex vivo showed greater tumor signal and contrast when mice were administered NIRF dyes that were covalently conjugated to (NanoCy7.5) or physicochemically entrapped in (NanoICG) hyaluronic acid (HA) NPs, compared to free dyes. These results show the potential to use these NPs as tools to detect the margins… Show more

“…Hydrophobic and amphiphilic molecules, such as ICG, can be loaded into HA‐PBA NPs and retained in the hydrophobic pockets through π–π stacking (Svechkarev, Kyrychenko, Payne, & Mohs, ). Compared to free ICG, NanoICG provided up to 2.9‐fold higher intraoperative contrast and improved surgical outcomes in breast, pancreatic, and prostate tumors (Hill et al, , ; Qi, Chen, et al, ; Souchek et al, ; Wojtynek et al, ). Others have improved the tumor uptake of ICG with active targeting ligands.…”

“…Compared to free Cy7.5, NanoCy7.5 provided 14.8‐fold higher contrast in breast tumors. This is a product of not only the high QY of Cy7.5 but also direct conjugation of the dye to the HA NP, minimizing the amount of free Cy7.5 escaping from the nanoformulation (Hill et al, ; Kelkar et al, ; Souchek et al, ). Also, NanoCy7.5 was combined with HA‐PBA‐GdDTPA in a mixed‐micelle formulation, termed self‐assembled multimodal imaging NPs (SAMINs), for dual‐modality MRI‐NIRF imaging of breast tumors.…”

“…HA-binding receptors, such as RHAMM and CD44, have been shown to be overexpressed on various cancer cell surfaces, further expanding the broad applicability of HA-based nanomedicines for active tumor-targeted drug delivery (Jiang et al., 2012 ). Additionally, HA exhibits low accumulation in liver because of weak specificity to its binding site in this organ, thereby promoting accumulation of HA-based nanomedicines in tumor tissue (Hwang et al., 2017 ; Souchek et al., 2018 ). Multiple stimuli-responsive nanomedicines based on HA have been developed for cancer therapy, such as an enzyme-responsive HA-based nanogel for drug delivery that is preferentially internalized by CD-44-overexpressing cancer cells (Yang et al., 2015 ).…”
